Description
Technical field:
The present invention is relevant with packing box, and is especially relevant with compound packing box and the manufacture method thereof of the biaxially oriented polypropylene film of color printing and cardboard.
Background technology:
Packed in cases is the packing that all commodity all be unable to do without, in order to improve the value of commodity, upward century-old messengers for the raising aesthetic property that reduces cost, gain in strength on traditional cardboard box printing is made, enlarge use and range of application and raise the efficiency, carried out many research and improvement.
General system case production process is that paper roll prints continuously, improves the printing aesthetic property and the maximization of carton.But traditional carton scope of application is very limited, and such as the packing of chilled food, marine product, fruits and vegetables, because carton is non-moistureproof, uses at freezer and have to carton is come with waxdip moistureproof, causes the carton cost too high and be subjected to promoting restriction.In the printing on carton top layer and the continuous printing of coil paper, because the thickness deviation of cardboard surface too big and coil paper is too coarse, not bright and clean, lackluster, the fineness and the gloss of printing, fineness does not reach the demand of commodity, people bring into use the cast polypropylene film now, polyester film, biaxially oriented polypropylene film removes the printed patterns on carton top layer of the cardboard of compound one by one or topped above-mentioned cut-out after its surface is coated with a layer binder with coating method, make more gloss of printed patterns, bright and clean and attractive in appearance, the intensity and the moistureproof performance of carton have also been increased simultaneously, also enlarged the scope of application, printed patterns on the cardboard and top layer, utilize plastic foil coated binding agent will be one by one cardboard and top layer compound or topped mainly be to have utilized existing conventional equipment and technology also to obtain to improve the decoration level really and improve that packing case is worth and the effect of commodity value such as OPP laminating machine or CPP laminating machine.
But if printed patterns is printed on the plastic foil, particularly on the biaxially oriented polypropylene film, though pattern be imprinted on film outer surface or in the surface, because the bright and clean and saturation degree of its printing-ink adds the fineness of film and the refraction action of film, undoubtedly can be more exquisite, rich merchant's product value more than the printing on paper.
Therefore with the compound fancy packing box of cardboard surface layer paper, and can't obtain behind the pattern that is beautifully printed on biaxially oriented polypropylene film or the Dampler Ace compound and make packing box after we pass through the coated binding agent still seeing the pattern that is beautifully printed as possible on the surface layer at cardboard in advance on the market with the biaxial stretching film of layer of transparent or casting films so far with the surface layer paper of packing case.
